The performance panel lets developers see how quickly their page is loading and rendering. It allows developers to find bottlenecks in their code and optimize their pages for better performance. 

  • The Console panel 

The Control panel lets developers run JavaScript code on their pages. It also helps to test code snippets or debug the code. 

  • The Application panel 

The Application panel lets developers inspect the application state of the page. They can also view and edit localStorage, cookies, and sessionStorage. 

  • The Memory panel 

The Memory panel lets developers see how much memory their page is using. Developers can track down memory leaks and optimize their code for better memory usage. 

What is web accessibility? 

The ability of a website to be accessible to people with disabilities is called web accessibility. It is the practice of ensuring that no brocade prevents the interaction of people with physical disabilities with the web. Disabilities may include visual, hearing, neurological, cognitive, and motor problems.

There are many assistive technology tools available to help specially-abled people. These technology tools make it easier for them to navigate and interact with a website. These assistive tools involve alternative keyboards, screen readers, eye-tracking tools, screen magnifiers, etc. After getting a brief idea about web accessibility let us know why it is important. 

Why is web accessibility important?

Many technologies are available to remove the barriers for disabled people to digital access. These technologies are important as everyone should enjoy access to information. These benefits ensure that everyone can use the internet and have a good web experience. 

Having a good accessibility strategy also has business benefits. Accessibility is a component of design and development. It touches almost every element of the web’s creation. Accessible websites can have better search results, increased audience reach, reduced maintenance costs, and demonstrate corporate social responsibility. Therefore, having a well-designed and accessible website does not just make the website accessible to those with abilities but improves the user experience for everyone. 

Leveraging Chrome DevTools to improve web accessibility

Leveraging the different accessibility-related features in Chrome DevTools helps to improve web accessibility. Some of the accessibility-related features in Chrome DevTools are mentioned below: 

Lighthouse Audits panel- The Lighthouse Audits panel is powered by aXe. It is a good tool for examining and improving web accessibility. The audit report is informative. It states what failed, and why it failed and provides links to resources to help the user learn more.

Element inspector- The inspect element feature in DevTools gives users access to a tooltip with accessibility features at a glance. It shows up whenever users inspect an element on a web page. It displays the following properties:

  • Contrast ratio-  Contrast ratio measures the difference in brightness between the background and foreground colour of the text.
  • Role- Role displays the function of the element. It shows ‘generic’ for elements like <span> and <div> without semantic meaning.
  • Name-Name displays the visible text.
  • Keyboard-focusable- Keyboard-focusable shows if users can focus on an element using the keyboard. A grey colour shows that an element is not keyboard-focusable. The green colour shows that the element is keyboard-focusable.

Contrast ratio- This feature of Chrome DevTools measures the difference in brightness between the foreground and background colour of the content on the web page. This feature is helpful when choosing the colour scheme of web pages during the design phase. Using the colour picker helps to choose colours that meet the standard.
